Ben Wilson, energy spokesperson at Gocompare.com, said: “With spring just around the corner, this is the time of year where many people begin turning off their heating and start paying less attention to their energy bills.

HOW TO FIND A CHEAPER ENERGY DEAL

FIRSTLY, you’ll need to have a recent bill to hand. This will have all the details you need, including the name of your tariff and your recent spending on gas and electricity.

Use a comparison website like uSwitch.com or Energyhelpline.com. Other services like MoneySavingExpert’s Cheap Energy Club will let you set up an email reminder that will alert you when cheaper deals become available.

Compare prices and before you switch check with a cashback website, like Quidco or TopCashback, to see if there’s a deal you can use to increase your savings.

Wilson continued: “However, taking your eye off the ball could be a costly mistake as 30 fixed rate tariffs end on March 31 resulting in an average price rise of £269.

“Comparing and switching tariffs is quick and easy, you could even save as much as £305 a year by doing so – money that could be better spent on getting out and about with the family over the spring bank holiday weekends.”

Not all bills coming to an end this month will result in homeowners paying more.

Some current deals are actually more expensive than the energy firm’s SVR, so your bills could fall when your deal ends.
